cabled access points have higher per-subscriber costs However, installing multiple antennas on existing APs allows the leveraging of past investment in access points and related site costs Furthermore, since little or no cabled infrastructure needs to be installed, deployment may proceed quite fast, but the capacity for adding new customers is limited In any case, current BWA system capacity is limited by the amount of radio spectrum available for broadband services (eg the fraction of the spectrum allotted via government spectrum licensing polices to broadband services) and the extent to which clever system design can increase the performance achievable from a given amount of bandwidth As already pointed out, a possible option for increasing performance is to resort to picocellular clusters, so as to increase the frequency reuse The need to deploy more transceivers (and install wireline to connect them to the provider s network) makes the improvement costly, so that picocellular systems have costs dominated by labor costs approaching those of cabled systems As already pointed out, an emerging option is to exploit space time processing techniques combined with multi-antenna transceiver architectures, which hold the promise of roughly a factor of 10 improvement in the user throughput and/or frequency reuse These emerging techniques rely heavily on improvements in the processing power of application-speci c integrated circuits (ASICs) or digital signal processors (DSPs), enabling the real-time signal processing to be performed in affordable hardware This contribution supports the conclusion that even though today s 4G technology may be still immature, it is relatively safe to predict that there will be a growing demand for BWA to portable and mobile devices This is because of fundamental market trends toward smaller personal computing and communication devices (eg palmtops, PDAs) that, in the long term, are likely to account for the majority of end user devices, in contrast to the fast-growing minority that they represent today The authors opinion is that, once untethered computing devices become ubiquitous, today s PC-centric access network (HFC, DSL, and so on) will have to evolve toward hybrid wired and wireless networks, while the last mile, last 100 m, or even last 10 m will be mostly wireless The cost and performance of broadband wireless networks will thus be crucial to the user s overall experience In this context, it is worth noting that there are still signi cant challenges associated with delivering true broadband services, as de ned in this chapter, to mobile devices Research and development (R&D) challenges faced by developers of 4G wireless standards include higher aggregate rates (up to 100 Mbps), maintenance of service quality under mobile fading conditions, integration of mobile and xed network architectures and greater spectral ef ciency, capacity and scalability The examined different wireless broadband technology options are different in detail Furthermore, 80216-based systems may be appealing for supporting market entry by providers that have no access to existing wireline assets On the contrary, in the most remote areas, a small fraction of users may best be served by LEO satellites, where the very high xed cost of launching satellites is offset by the very low per-passing costs Finally, 4G WLANs represent an important example of how a solution to a speci c problem the wireless extension of Ethernet could become the basis to provide ubiquitous IP-compliant broadband wireless access to mobile users However, four main technical challenges, namely: ease of use, security, mobility and network management, are still to be overcome before accomplishing this task Furthermore, the economic viability of the public hotspots market is still unclear.

Most of this is straightforward The consumer checks that m_q u e u e Count ! e before removing an item from the queue If the queue is empty, the thread must wait for a producer to set the event Clearly the consumer needs to exit the mutex before waiting, otherwise no producer would be able to enter its critical region and enqueue data As soon as the consumer wakes up, it must acquire the mutex again The check for the queue being empty is done in a loop because although the thread has awakened because a pro

call De q u e u e i n the meantime This thread acquires the mutex before the awakened thread and dequeues the element We must ensure in this case that the awakened thread sees that the queue is empty and goes back to waiting again We have to be careful to avoid deadlocks in this design These might be caused by threads going to sleep and not being told properly that new items have arrived (This problem, referred to as "lost wakeups," is described at great length in 1 1 , Concurrency Hazards; it is perhaps the most common control synchronization pitfall that people face) To avoid deadlocks in this particular case, we must ensure that when an empty queue is noticed (while the mutex is still held), the consumer releases the mutex and waits on the event atomically, accomplished with the call to

The beauty of offline analysis is the ability to provide quality guarantees For PAR, the analysis report is simply numbers, the PAR rating for the video sequences Since the PAR rating has a close correlation with subjective human-eye measures, it can operate unmanned as an effective automatic eye to monitor MPEG video quality It can be carried out automatically overnight, and any out-of-limits material can be flagged for corrective action the next day One fundamental advantage of this is the ability to check picture quality and consistency PAR alone is a great step forward, but for deeper analysis, the ability to see encoding parameters on a picture-by-picture basis helps enormously Mosalina, a personal computer (PC) software application for MPEG offline analysis, has been developed by Snell & Wilcox as a monitoring tool for just this purpose Good downconversion is very demanding on processing power For example, going from a 1,080 lines standard (now used in most HD production systems) down to 480 lines requires extremely complex filters Very, very few PCs are capable of running any such conversion in real time, certainly not while retaining much of the original quality A dedicated HD downconverter that renders as much detail of the HD original into the standard-definition (SD) result is a valuable asset This can enable the opening of new businesses in the expanding areas where HD masters are used Since the images have little noise, they compress easily and provide the double benefit of good pictures and low bit rates

The structure of this code is nearly identical to the managed implemen tation: there's a little more state management minutia and the optimization to avoid unnecessary pulses has been omitted for brevity Prior to Windows Vista, this would have been far more difficult to implement, requiring you to use heavyweight semaphores, mutexes, and / or events instead
